Document Summary
Organ: consists of several types of tissues that together carry out particular functions. Tissue: group of cells consisting of one or more cell types that together perform a specialized function. Basic morphology of vascular plants reflects their evolution as organisms that draw nutrients from below ground and above ground. They are organized into a root system and a shoot system. Roots rely on sugar made by photosynthesis in the shoot system and shoots rely on water and minerals absorbed by the root system. In eudicots, a taproot system provides anchorage and consists of one main vertical root that gives rise to lateral roots which improve anchorage and water absorption. Adventitious roots that arise from stems or leaves. Root hairs near the root tip increase the surface area of the root. In most plants, absorption of water and minerals occurs near the tips of roots. Alternating system of nodes points at which the leaves are attached.
